The previous 11 consecutive rain-free days may have lulled you into complacency, but as anyone who tried (and failed) to get a cab this morning rudely discovered, April showers in New York City require the right gear. Still, no matter how waterproof a raincoat is, it can't keep you dry if you don't have it with you. That's one reason we love the new "packables" jackets from Mackage. The toppers, which come in a short motorcycle version and a longer, knee-length iteration, roll up and fit into a tiny pouch concealed inside the jacket, so you can keep it tucked in your handbag for when the need arises. And unlike most other foul-weather gear, form is not sacrificed to function. Both styles are made of a high-tech fabric that bears no resemblance to those icky plastic ponchos, and each has dainty puffed sleeves, linear stitching, and subtle leather accents at the wrists. Plus, their sleek fit won't water down a girl's figure. The city slickers are available now at Saks Fifth Avenue for $286 to $330, so pick one up and don't get left out in the rain: It's here for most of the week.
